2 1 The new standard AMK collectors the new standard in using solar thermal energy, who pioneered the 360 absorber technology and developed the OPC10/15 high-performance collectors, recognised the advantages of three-dimensionally shaped absorbers more than ten years ago. Being awarded with the gold medal at the Exhibition of Inventions in Geneva, Switzerland, was the logical result of a brilliant implementation. AMK-Solac Systems AG has over 15 years of experience in developing and producing evacuated tube collectors. AMK collectors are developed and produced in Switzerland. The quality is aligned with European standards of quality (Euro-Norm). -Products All AMK products have proven to be outstanding through maximum performance at minimum dimensions. In all our product series, the surface area of the absorber is larger than the gross surface area of the collector. This intentional target of maximising the absorber surface area is combined with the optimised reflectors to guarantee the maximum absorption of direct and diffuse radiation. All AMK collectors are equipped with evacuated tubes developed by AMK. AMK vacuum tubes have a nine-layer, highly selective coating, and vacuum loss is avoided completely due to the mechanical vacuum insulation. Did you know that the installation costs for conventional collectors can be up to 70% of the price of the collector? That is why AMK products are very easy to mount. We offer you optimised mounting systems for all kinds of applications (pitched roof, flat roof, facades, folded seam roof, fibre cement roof, installation of the collectors in open spaces). At the International Fair of Installation Technology and Industry (March ) in Poznan (Poland) OPC15 Edition EU21 has won the gold medal for a technical innovative development In terms of performance, quality, easy installation and flexibility, AMK collectors represent a new standard. AMK collector technology is protected by patent. Application areas for AMK collectors include: < Standard hot water heating DRC, OPC, OTC < Auxiliary heating DRC, OPC < Process heat recovery OPC < Refrigeration for air-conditioning systems OPC supported by absorption cold generation < For single-family homes, apartment buildings, DRC, OPC, OTC hotels, commercial and industrial properties eading through experience

3 2 The advanced absorber tube A tube for all kinds of weather throughout the entire year Our 360 absorber tube uses solar energy efficiently throughout the entire year and provides a building with heat even when the weather is cloudy. Due to the 360 technology, the absorber collects direct and diffuse radiation to a much greater extent when compared to other collectors. In combination with the vacuum insulation, our 360 absorber tubes have reached previously unknown levels of performance. The construction prevents heat loss even at temperatures below zero. The vacuum between the glass tubes that are fused together cannot be broken, and the insulating effect remains unchanged. This vacuum enables the 360 absorber tube to return consistently high output data over the entire service life of the tubes. Diffuse radiation Outer glass tube Vacuum (insulation) Absorber (9-layer coating) Inner glass tube Heat conduction plate Copper pipes Heat transfer fluid From the sun to the 360 absorber tube... Solar radiation both direct and diffuse penetrates the outer glass tube and is collected by the ninelayer coated, black absorber on the outer surface of the inner glass tubes....and from the tube to the solar circuit The 360 absorber tube is separated from the solar circuit completely. The collected energy is transferred to the close-fitting aluminium plate and to the copper pipes filled with heat transfer fluid. Very large contact surfaces facilitate a rapid energy transfer.

Inefficient heating systems are no longer needed. This combination collects highly useful energy from the sun, even at sub-zero temperatures in winter or under cloudy or rainy conditions. Mar Apr May Jun Jul Aug Sep Oct Nov Dec Additional benefit of DRC collectors Adva < The absorber tube is a uniform glass body. No metal-to-glass bonding. < The vacuum remains unbroken as an excellent insulation over the entire product life. < 360 absorber for the greatest possible surface area for energy absorption, utilises up to 80% of diffuse radiation. < The efficiency remains at a constant, high level throughout the product life because the insulation and the absorber layer do not degrade. < Damage can be done to the tube only mechanically. A tube that loses vacuum, even without visible broken glass damage, can be detected immediately by the white condensation of water vapor inside the tube. This detection eliminates any gradual yield loss of the solar system. < Nine-layer, highly selective aluminium-nitrite coating.

4 The collector for every budget Minimum loss of energy through integrated hydraulics and vacuum insulation Maximum energy yield through 360 absorber tube and parabolic reflector The 1/2 collector hydraulics minimises energy losses by having no external piping and by having the inlet and outlet for the solar water circulation on the same side. With 1/2 hydraulics, it is possible to have the largest systems with the lowest pressure loss. The collector hydraulics are fully integrated, enabling complete flexibility in attaching the hydraulics. Simple connection under balanced-pressure conditions. With the option of connections on the same or opposite sides for supply and return. Piping losses are minimised in the DRC because the piping is integrated into the collector. 1/2 dual tube system for small and largescale systems minimal pressure loss 2 pre-installed sensor sleeves Integrated collector hydraulics no external piping best insulation possible parallel connections Quick installation single-sided connection in and out on the same side only one roof penetration The large tubes and the reflectors adjusted to them enable the DRC to gain large amounts of energy from direct and diffuse solar irradiation. The large-sized absorber surface area is very important. AMK provides the DRC10 collector with an absorber surface area of 2.73m 2 for 2.04m 2 of collector surface area. AMK is the only manufacturer that has a greater absorber surface area in comparison with the gross surface area in all its products. This design makes it possible to use diffuse energy irradiation optimally.

5 4 Efficient modular installation system DRC the collector with the simple, cost-saving installation A roof is a roof that is why DRC collectors are mounted on the roof, not into it! DRC collectors stand out not only because of their top-line quality but also their excellent design. At not even nine centimeters in height, they look elegant yet functional on every roof. Even large DRC collector arrays can be connected on one side. This means that the roof is penetrated at one single position for the piping to enter the house. No external piping is necessary on the roof. Multi-functional sliding rails make installing the DRC collectors extremely easy. At the same time, the hydraulic connections of the collectors are be screwed on using standard tools no soldering, no welding, no special parts. All parts and steps are self-explanatory, and there is nearly no Of course, the DRC mounting system is also available for flat roofs, fibre-cement roofs and wall mounting. On a flat roof, the DRC collector comprises a mounting rail with flexible options for angle adjustments; the mounting is even faster than for a tiled roof. taken into account.

6 5 Intelligent DRC system technology DRC collector provides more advantages for users Our DRC collectors produce maximum power output when properly integrated into the building s service technology. DRC collectors are burner and heaterfriendly; they last longer, run with less faults and require less maintenance because the inefficient stopand-go operation of the burner is avoided. Additional benefits in all areas: lower operating costs and high energy savings (70 80%, depending on the system combination), longer useful life and thus lower investment costs. CW WW warm cold Oil/gas heating and DRC collectors Turn off your oil or gas burner for six months! Then your burner will run more effectively during the winter and transitional periods. Maintenance efforts, investment and consumption of oil or gas decrease. heating boiler expansion tank Wood heating and DRC collectors The ideal combined system: wood stove with a storage tank readily available that can be used for solar energy. Additionally, the consumption of firewood is greatly reduced which simplifies handling as well. Heat pumps and DRC collectors The combination of a solar system and a heat pump uses electrical energy even more efficiently. The heat pump is not needed in summer and is supported by the solar system in winter. That pays for itself twice over. What is your DRC combination? DRC collectors optimise your building s technology. They can be combined with conventional and new renewable energy systems such as controlled ventilation systems. Take advantage of a DRC system combination!
